  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.

  • What are the gotchas of using statically linked libraries in serverless platforms such as Google Cloud Functions ?

    5 septembre 2017, par Dzh

    Libraries such as ffmpeg-static upload statically linked binaries onto container.

    I wonder what are the drawbacks of using this approach ?

    Does the library size counts against your memory use (it’s billed by GCloud) ?

    Does it slow down the container ? Perhaps some future-proofing issues ?

    Edit : Found something of a related (I wanted to setup OpenCV) on AWS blog. It doesn’t explain drawbacks, just shows how to do it exactly.

  • ffmpeg : overlay video on top of a cropped video, map the overlay audio, cut the base video to the overlays length

    14 mars 2023, par roku

    I'm trying to overlay a video on top of a base video which is cropped to a shorts video format (standing phone). The overlayed video should be centered on top of the base layer. The base video's length should be reduced to the overlay's length. And I want to save only the overlay's audio.

    


    I've tried a bunch of stuff without much success. The current state of my ffmpeg command is this :

    


    ffmpeg -i overlay.mp4 -ss 00:00:00 -to <insert base="base"> -i base.mp4 -map 1:v:0 -map 1:a -vf "crop=ih*(9/16):ih" -crf 21 output.mp4&#xA;</insert>

    &#xA;

    But this only gives me the cropped version of the base video. So my questions are :

    &#xA;

      &#xA;
    1. How can I figure out the base video's length ?

      2. &#xA;

    2. How can I actually overlay (not map) other video on top of the base video ?

      3. &#xA;

    3. How can I map the overlay's audio ? Since -map 1:a the base's audio and -map 0:a says : "Stream map '0:a' matches no streams. To ignore this, add a trailing ' ?' to the map."

      4. &#xA;

    &#xA;

    Any help is appreciated.

  • Create a video file of multiple images [closed]

    2 juillet 2012, par idish

    I am trying to create a video in android that displays the chosen images by me. one by another. I've heard of ffmpeg and Dolphin player open source code. I'd like to know the cons and pros of them. Is ffmpeg is easy to work with ? and what about the Dolphin player ?
    Another thing I undestand is that ffmpeg is programmed by command line ?
    Anyway, I would like to hear some reviews about ffmpeg or the Dolphin Player.
    Is it possible to embed the ffmpeg to my mono for android application ?

    Thank you.
